GIVING BRAINLIEST TO WHO ANSWERS THIS EASY MATH QUESTION FIRST... A trapezoid has an area of 50 in2. If the bases are 12 and 8 inches, what is the height?

The height is 5in :)

Step-by-step explanation:

height = 5 in

Step-by-step explanation:

Area =h x (b1+ b2)/2

50 = h x (12 + 8)/2

50 = h x 10

h = 5

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
